4G0 ELEMENTARY CHEMICAL MICROSCOPY 



(d) Fractionally sublime Naphthalene. 



(e) Fractionally sublime Indigo. 



4. Distillation. See page 292. (a) Use the apparatus shown in Fig. 153. 

 Drive off NH 3 from NH4CI, using NaOH. In the condensate test for NH 3 using 

 H 2 PtClG (see page 327). 



(b) In like manner distil off CH3COOH from CHsCOONa and H 2 S0 4 , using 

 AgN03 (see page 421) as the test-reagent.
